If anyone was a candidate to prove the auteur theory, it would be Alfonso Cuarón. “Gravity” producer David Heyman told Indiewire“He [Cuarón] has a deep understanding of every aspect of the filmmaking process. He’s the first assistant director, he knows the camera, the lenses and the lighting, the writing, the editing, he has an incredible knowledge of music and much more. “
But even with all that knowledge, Cuarón struggled to create the shot that was integral to Dr. Ryan Stone’s (Bullock) character arc. The moment in question is a lengthy one, one where Stone realizes that the Soyuz spacecraft has run out of fuel and shuts off the ship’s oxygen supply, so she’ll slowly die inside.
Cuarón, who co-wrote the film with his son Jonás, explains Vulture Why is that the most difficult scene to write in the movie? “It was a difficult script to write because so much needed to be conveyed and you only had one character,” Cuarón said. “The challenge was to reconcile this sudden will to live with the backstory we developed about Ryan’s dead daughter.”
That’s when collaboration became key and the film’s co-star, George Clooney, stepped in to save the scene.
